FASTENING FOR SHOE-SOLES.

. SPECIFICATION forming part of Letters Patent No. 415,771, datedNovember 26, 1889.

Application filed March 8, 1889. Serial No. 302,577. (No model.)Patented in France November 7, 1888, No. 193,961.

To all whom it may concern:

Be it known that I, FRANZ CARL HEINRICH FICKERT, a subject of the Kingof Prussia, re,

siding at Schwerin, in the Grand Duchy of Mecklenburg, German Empire,have in vented an Improved Fastening for Boot or Shoe Soles, (for whichI have obtained Letters Patent in France, No. 193,961, dated November 7,1888,) of which the following is aspecification.

This invention relates to an improved manner of fastening soles to theuppers of boots or shoes.

The invention has for its object to provide av fastening' that firmlyunites the sole to the upper and which doesnot weaken the leather.

The invention consists in the various features of improvement, morefully pointedout in the claim. Y

In the accompanying drawings, Figure l is a bottom view of part of ashoeprovided with my improvement. Fig. 2 is a section on line 'y y, Fig. I,partly in side view. Fig. 3 is a vertical section through one of thefastenin gs. Fig. 4. is a plan of the same. Figs. 5 and G are a sectionand plan, respectively, of a modification. Fig. '7 is a section ofanother modificationand Fig. 8 a plan of plate b2.

In Figs. l to et there are placed below the insole a the sheet-metalclasps or plates b, the ends of which are bent up at right angles andare passed through slits cut into the insole. Next these ends of claspsb are bent down over a small sheet-metal plate c, and then they areflattened down on the upper surface of the insole, as shown in Figs. 3and 4. 4In the center of the metal clasp b a small hole is provided,through which a screw d enters after traversing the sole A and theuppers.

The screw d is firmly grasped by the plate b, which acts as a nut, and asolid, strong, and lasting connection is thus established between theseveral parts traversed by the screw. A suitable number of screws d andplates b are provided to secure the sole to the uppers and insole. Bythis fastening the elasticity of the leather is not in any mannerimpaired.

The modification shown in Figs. 5 and 6 consists in substituting forclasp b a clasp b', having two lugs b4 at each bent-up end. These lugsafter passing through the insole are bent down, and are then bent upagain to enter into the leather lot` the insole, as clearly shown inFig. 5.

In Figs. 7 and 8 the plate c is omitted,and in lieu of the clasp b afork-shaped clasp b2 is used. g through slits in the insole, after whichthe prongs are flattened down and are then bent up again to enter theleather. This mode of securing the metal plates is more particularlyintended t'or boots and shoes of light make. If desired, a sole e' maybe placed upon the insole to protect the foot from contact with platesb.

I claim as my invention- The combination of sole A and insole a with aperforated clasp having bent-up edges that are passed through theinsole, and with a screw d, passed through the soles and said clasp,substantially as specified.

In testimony whereof I hereunto sign my name, in the presence of twosubscribing witnesses, this 12th day of February, 1889.
